MADISON, Wis. -- About one-quarter of the 911 call placed by Brittany Zimmermann's fiance after he came home and found her killed last April was omitted by Madison police before being released to the media.

The heavily redacted call was released on Thursday under court order to WISC-TV and three other media outlets -- the Wisconsin State Journal, the Milwaukee Journal Sentinel and WTMJ-TV in Milwaukee -- that sued Dane County for release of a 911 call apparently made by Zimmermann herself before she was killed and related documents.

Last month, a Dane County judge denied the release of Zimmermann's call but ordered county officials to release her fiance Jordan Gonnering's 911 call after police redacted any information they believe would harm their investigation into who killed Zimmermann, a 21-year-old University of Wisconsin-Madison student from Marshfield, in her campus-area apartment.

More than 1 minute of the 4:44-minute call by Gonnering was deleted prior to release and the remainder reveals little or no new information about Zimmermann's death or the crime scene. Gonnering called 911 shortly after 1 p.m. on April 2 -- about 50 minutes after Zimmermann apparently dialed 911 from her cell phone, presumably for help.

The unidentified female 911 dispatcher who Gonnering spoke with first asked him numerous questions about his location in the 500 block of West Doty Street and he states "ambulance needed." The dispatcher then asks what happened.

"I just came home --- the door's busted in and my girlfriend's been shot," Gonnering said.

The dispatcher then asks if Zimmermann is conscious. "No, she's not," Gonnering said.

At that point, the tape is redacted for a few seconds before the 911 operator asks if he's safe. "Yes, I think so," he said.

The dispatcher then asks, "Is the person who did this still nearby?" The tape is then deleted for 17 seconds.

Numerous redactions follow, interspersed with 911 operator's questions that include "Is there serious bleeding?" and "She's been what?"

The operator tells Gonnering to take his phone to Zimmermann so she can tell him how to help her. The dispatcher also asks him if Zimmermann could have "done this herself."

"No, she couldn't have", Gonnering said, adding, "They're gunshot wounds."

The operator told him help was on the way and asked him if Zimmermann is breathing at all. Another deletion then occurs.

The call ends with the dispatcher telling Gonnering to leave the house because authorities have arrived. Gonnering tells the operator an officer has told him to hang up and he then does after saying, "Good bye."

Gonnering and the Zimmermann family earlier objected in court to the release of either 911 call.

Professor John Pray, of the University of Wisconsin-Madison Law School, said that one reason 911 calls are edited before being released is that investigators say releasing the entire call would jeopardize their case.

Pray spoke with WISC-TV in general terms about the release of any 911 call and said his comments aren't specifically addressing Gonnering's 911 call.

Pray said that sensitivity to the victims and families involved might lead to some editing, but he pointed out that it can be difficult to balance.

"From the public standpoint, I think it's important to have some oversight of the police or anyone doing those kinds of jobs. If there's public oversight, people do their jobs better and know (they) better be straight and narrow because the public will see this," Pray said.

Search warrant documents filed in court and inadvertently left unsealed by city and county officials last month said screaming and sounds of a struggle can be heard on Zimmermann's call to 911.

A different 911 dispatcher who took Zimmermann's minute-long call has said she didn't hear anything that indicated an emergency and thus never sent the police. She failed to return Zimmermann's call in violation of 911 center protocol because she took another 911 call and apparently forgot.

That dispatcher left the 911 center shortly after the incident in a pre-planned transfer to the county's Child Support Services. Last month, the county gave her a three-day suspension for failing to call back Zimmermann.

The dispatcher, Rita Gahagan, is fighting that, though. She recently filed a grievance asserting the discipline was without "just cause," and issued under media pressure.

Search warrant documents inadvertently unsealed recently include medical reports stating Zimmermann was repeatedly stabbed as well as beaten and strangled and that the attacker broke through the front door.

Numerous valuable items weren't taken from the apartment, including a diamond ring, a wallet and purses, the documents said.

Police have said they have no key suspects in their ongoing investigation.
